Synthesis
Reaction of ethylamine with 2,5-dimethylpyrazine 1-ethyl-1,4-dihydropyrazine is produced by reacting ethylamine with 2,5-dimethylpyrazine, which is another organic compound.
Characteristic smell
Nutty or cocoa-like The compound is known for its strong, pleasant aroma, which is often reminiscent of nuts or cocoa.
Precautions
Handle with care and use in controlled concentrations Due to its potent odor, it is important to handle 1-ethyl-1,4-dihydropyrazine carefully and use it in appropriate concentrations to avoid any adverse effects.
Check Digit Verification of cas no
The CAS Registry Mumber 7466-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,6 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7466-71:
(6*7)+(5*4)+(4*6)+(3*6)+(2*7)+(1*1)=119
119 % 10 = 9
So 7466-71-9 is a valid CAS Registry Number.

Pyridine Nitrogen Reactivity
Johnson, David,Roberts, Ian,Taylor, Peter G.
, p. 409 - 413 (2007/10/02)
Pyridinium pKa values and rates of quaternization with ethyl iodide in various solvents are used to evaluate the effect of substituents on the pyridine nitrogen reactivity.Substituent effects on nitrogen reactivity are found to be intrinsic properties of the pyridine system independent of specific reaction type or solvent.The relevance of hydrogen-bonding in methanol and its influence on pyridine quaternization is discussed.The influence of potential resonance acceptors is shown to be due to their inductive effect alone, and the general question of the applicability of the dual substituent parameter equation to substituent effects on nitrogen reactivity in pyridine is considered.
